Description

Digital stand-alone unit drives the comber

technical field

The invention relates to a textile machine, in particular to a combing machine driven by a digital independent unit.

Background technique

In the prior art, the cotton textile industry generally uses a comber to remove wastes such as linters and impurities in the cotton fiber, and at the same time, the cotton fiber is carded to make the cotton fiber parallel and straight. The process of the combing machine is a process of periodically combing the two ends of the cotton clump respectively, and then sequentially joining them into a cotton web to continuously output the combed sliver.

During the combing process of the combing machine, the cotton roll is intermittently fed into the nipper mechanism composed of upper and lower nippers. The carding needle faces the front end of the cotton layer to comb thoroughly, so that the fibers are straightened and parallel. After carding, the front swing of the nipper gradually approaches the separation nip composed of the separation roller and the separation top roller. During the forward swing of the nipper, the upper nipper is gradually opened, and the combed hairs straighten forward. At the same time, the cotton web held by the separating jaws of the previous cycle is poured into the machine for a certain length because the separating roller reverses first. , so as to engage with the combed front beard. The separation roller turns from reverse to forward rotation at the specified time. When the forward rotation accelerates to a certain degree, the ends of the hairs outside the nipper just reach the separating jaws, so that the ends of the combed hairs are the same as the cotton web in the previous cycle. The tail ends of the fibers are joined together and enter the separation jaw together, and the fiber tail ends are pulled through the top comb needle row, so that the tail ends are combed by the top comb. The combing machine continuously repeats the above-mentioned cycle of feeding, carding and separating and joining to form continuous combing production.

The executive mechanism of the cotton combing machine in the prior art all comprises parts such as nipper part, cylinder, hairbrush, cotton feeding roller, front and rear separation roller, lead-out roller, table pressing roller, drafting roller, sliver coiler. In the existing cotton combing machine, the described hair brush is driven by a hair brush motor alone, and the hair brush transmission mechanism drives the hair brush to rotate at a high speed to clean the cylinder in the combing machine, while the other functions of the combing machine The mechanism is generally driven by a main motor through a transmission system, and the main motor and the brush motor operate independently.

This kind of mechanical transmission structure not only ensures the reciprocating motion of the top comb and nipper, but also ensures the movement of cylinders, output rollers, drafting rollers and other components with different speeds. Not only the transmission line is long, the transmission mechanism is complicated, and shock vibration is easy to occur It is unfavorable for high speed, and it is difficult to flexibly adjust the combing process parameters for different cotton fiber varieties to enhance the spinnability of the combing machine; the movement of the separation roller cannot change its effective output length and determine the separation process requirements of different cotton fiber varieties. The most suitable process movement law; and the relative movement between the separation roller, the upper and lower nippers, and the cylinder cannot be independently adjusted and optimally combined. Although there have been combing machines driven by the main motor to drive the cylinder and nipper and the front and rear separation rollers are driven by another motor alone, this improvement only partially simplifies the transmission mechanism, and the nipper and cylinder The relative motion between them is still not adjustable in real time.

Contents of the invention

Beneficial effect

In the combined vehicle body of the present invention, the movements of the independent driving units in the combing process can be staggered mutually, so that one unit of the combing head can be designed to move forward while the other unit of the combing head moves backward, thereby effectively reducing the amount of combing. The vibration generated by the same-phase movement of the combing machine in the high-speed production process; at the same time, the independent unit drive is compared with the overall drive, and the single-machine drive power can be doubled, which can meet the drive requirements of the high-power high-speed reciprocating motion control of the whole machine. The take-up roller, cylinder, nipper shaft, brush, front and rear separating rollers, take-off roller, drafting roller and coiler are driven by independent motors, which greatly simplifies the transmission mechanism of the combing machine, which not only facilitates design and Maintenance, the most important thing is that the process movement parameters of each working part can be adjusted independently, which can greatly improve the spinning performance of the comber, and is conducive to the improvement of the quality of the combed sliver.
